RESILIENT SOLE PAD FOR SHOES.

Application filed August 23, 1927. Serial No. 214,851.

The present invention relates to improvements in foot-wear,particularly in the solepads of shoes, and it is the principal object of the invention to provide a removable pneumatic pad which can be inflated to any desired suitable degree for resiliently supporting the foot.

Another object of the invention is the provision of a sole-pad for toot-wear of simple and inexpensive construction, yet efliciently cushioning the foot to avoid falling arches, etc." I

A further object of the invention is the provision of a pneumatic sole-pad having a self-closing valve to avoid the escape of air after inflation, and equipped with a suitable valve, the parts being so constructed as to avoid injury to the foot or undue pressure against the same.

These and further objects and advantages of the invention will become more fully known. as the description thereof proceeds, and will then be specifically pointed out in the appended claim.

In the accompanying drawing, forming a material part of this disclosure:

Fig. 1 is a. fragmentary longitudinal section of a shoe equipped with a pneumatic sole-pad constructed according to the present invention.

Fig. 2 is a bottom plan view thereof, partly .in section.

Fig. 3 is a sectional view of part of the pad, illustrating the valve arrangement and the packing.

Fig. 4 is a fragmentary plan View thereof.

A shoe 10 has removably placed upon its inner solo a pad 11, having. substantially the shape of the sole, and adapted to be inflated by means of a removable inflation tube 12, the hollow stem 13, of which removably engages a suitable socket 14, in the pad. Intermediate its ends the tube 12 is equipped with the customary ball-valve 15 within a suitable r casing 16, and pressed against its seat by a spring 17.

A. suitable flap 18 within pad 11 is adapted to close the opening of the socket 14 after removal of the inflation tube, by the inner pressure prevailing in the tube after its inflation.

A valve 19 is arranged above flap 18 and has a socket 20 formed therewith into which the edged end of an operating handle 21 fits, to be frictionally held therein, and allowing a ready withdrawal of the same upon completion of the inflating process The device operates as follows:

The pad 11 is inserted into the shoe, so that it can be inflated by means of the inflation tube 1.2, having an outer flaring mouth 22. The escape of the air through the tube 12, is prevented by the ball-valve 15. Then the valve 19 is swung, by means of its handle 21, to cover the openings in the pad in sockets 1st and 20, and handle 21 and tube 12 are then removed. It will be clear that the pressure prevailing within the pad will press flap 18 against said valve and constitute an air tight closure, so that: no air can escape from the pad.

lVhile I have described and shown one example ot the practical embodiment of my invention, it will be clear that the same may be subjected to many changes. such as'fall within the scope of the appended claim without departure from the spirit of the invention and the principle involved.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is:

A pneumatic sole-pad for shoes adapted to be placed upon the sole of the shoe, and compri ing a socket adapted to receive the 1101- low stem of a removable valve-controlled inflation tube, a valve in said pad adapted to be frictionally engaged by the edged lower end of a removable operating handle to be operated thereby to close said socket, and a flap adapted to be pressed by the air pressure prevailing in the pad against said valve and socket to provide an air tight closure after removal of tube and handle from said socket and valve.

In testimony whereof I have afiixed my signature.

WILLIAM FISCHER.
